<p>PURPOSE:To provide air-conditioning and AC power supply driven through internal-combustion engine in which AC electric load machines can be operated stably without increasing output of the internal-combustion engine. CONSTITUTION:An internal-combustion engine 1 drives an AC generator 3 and the compressor 2 of an air-conditioner 20, while the AC generator 3 feeds commercial AC loads 32, 34 with power, and an r.p.m. sensor 6 detects r.p.m. of the internal-combustion engine 1. A compressor capacity/air-conditioning load reducing means in a controller 30 forcibly reduces the capacity of the compressor 2 and electrical air-conditioning load based on an r.p.m. signal fed from the r.p.m. sensor 6 upon drop of r.p.m. thus sustaining r.p.m. of the internal-combustion engine 1 within a predetermined range. Furthermore, the controller 30 increases AC power supply and sustains the voltage and frequency of the AC generator 3 within allowable ranges of commercial voltage and frequency.</p> |
